Answer:

Step-by-step explanation:
50 can be also written as
and the reciprocal means the inverse or to flip the fraction.
You can add 14 to the 9 to get pith of the problem so you'd be left with |2x+1| = 23 then it comes it quite obvious that X=11 because 2 times 11 plus 1 equals 23
Let
and
be the number of elves and reindeers, respectively.
We know that:
(so far 14 of them have arrived)
(each reindeer has 4 legs and each elf has two)
If we multiply the first equation by 2 we have
, and if we subtract this equation from the second we have
which implies
.
So, there are 5 reindeers and 9 elves (remember that they have to sum up to 14).
Answer:
- 8 points left and 7 points down
Step-by-step explanation:
Get the difference of one point on M and corresponding point on L, and find the difference of coordinates.
<u>Lets take top right points:</u>
<u>The difference:</u>
- -1 - 7 = -8 ⇒ 8 points left
- 2 - 9 = -7 ⇒ 7 points down
-2x^3 - 4x^2 + 4x
-2x^3 = -2x(x^2)
-4x^2 = -2x(2x)
4x = -2x(-2)
so GCF= -2x
-2x3 - 4x2 + 4x = -2x(x^2 + 2x - 2)
answer is B. -2x(x^2 + 2x - 2)
